I have a 2000 Pontiac grand am and I am trying to figure out a problem. Occasionally when I hit the brakes the brake pedal gets soft for a split secon and then it will be firm again. I have no leaks anywhere and I am clueless. Any help would ne awesome.

not very common but have been bit by this, a very loose front wheel bearing can cause the rotor to push the caliper back in causing a long travel on the pedal.. and it may not make noise.. might wanna jack up the car and check, just a thought. but is probably master cylinder issue
